Then why do you want Heliax? The primary advantage is lower loss. The
only other one I can think of is robustness against rodents. I use
LDF4-50 and LDF5-50 for 100m runs to my tower.

LDF4-50 is very nice cable, connectors are widely available at moderate
cost, and the loss is significantly lower than the best RG8-size coax.
I'm using LDF4 to go up the tower and LDF5 for the longer run on the
ground.
